BlueOptics MCP7900-X01AA-BL InfiniBand optický kábel 3 m QSFP 4xSFP+ konektor samec/konektor samec

The BlueOptics MCP7900-X01AA-BL InfiniBand Fibre Optic Cable is a 3 m connectivity solution featuring a QSFP connector on one end and four SFP+ connectors on the other in a male-to-male configuration. Designed for short-range, high-speed links in data centers and networking racks, this cable supports multi-lane 40G connections by combining four 10G lanes into a single QSFP interface. The construction follows MSA-compliant breakout design principles for interoperability with systems that support QSFP-to-4xSFP+ breakout connections.

Advantages

The cable provides a compact, low-latency connection for high-density networking environments, enabling straightforward linking of switches, routers and storage equipment that accept QSFP and SFP+ interfaces. Its passive design reduces power consumption and minimizes points of failure compared with active solutions. Manufactured to industry MSA guidelines and using quality components, the cable is intended to offer consistent electrical performance for short-distance 40G and 4x10G applications.

Suitable for

• QSFP-to-4xSFP+ breakout connections in rack and adjacent-rack topologies
• Short-range 40GBase-CR4 and 4x10GBASE-CR links within data center racks
• Connecting switches, routers, storage systems and InfiniBand-enabled hosts that support QSFP breakout
• Environments where low latency and low power passive cabling are required

Key specifications

• Length: 3 meters
• Connector types: QSFP (1 end) to 4 × SFP+ (other end), male-to-male
• Function: QSFP breakout supporting four 10G lanes (4x10G) / 40G aggregate
• Cable type: passive direct-attach/twinax-style breakout cable for short-distance electrical links
• Design standard: MSA-compliant QSFP breakout implementation

How to use

Install the QSFP end into the host device that provides the 40G QSFP port and insert the four SFP+ plugs into the corresponding SFP+ ports on the target device(s). Ensure both devices support QSFP-to-4xSFP+ breakout operation and the intended protocols (for example 40GBase-CR4 or 4x10GBase). Power down or follow hot-swap guidelines specified by your hardware vendor before inserting or removing the cable if required by the equipment. Verify link status in the devices' management interface after installation and confirm lane mapping and speed settings as needed.

Recommendations

Use this cable for short-distance connections inside racks or between adjacent racks where passive QSFP-to-4xSFP+ breakout is supported. Avoid routing across long spans—this cable is intended for short-range electrical links. Confirm device compatibility with QSFP breakout modes and check that the host firmware supports passive twinax/direct-attach cabling for reliable operation.
